Heuristics for Mobile phones
Dave Maruszewski & Shirley Carvalhedo
Heuristics for Mobile phones Mobile interactions are often small steps
in part oflarger user goals. Many interactions must be intuitive and
rapid. For example, if we are searching for an address when late for an appointment, we will have a low threshold for learning, registering or other obstacles to retrieving the data and locating our destination.

mobile experiences of different intensities and durations Mobile interactions can extend beyond the device Mobile interactions are often small steps in part of larger

able to provide services that redefine our social networks and the places we inhabit
Mobile phones will not be limited to the processing capabilities of the device
